SUPPORT FOR OVERHEAD ELECTRIC CONDUCTORS.

SPECIFICATION forming part of Letters Patent No. 422,164, dated February25, 1890.

Application filed January 2, 1890. Serial No. 335,587. (No model.)

To all whom it may concern: Be it known that we, CHAR-LES K. STEARNS, ofNewton, in the county of Middlesex and State of Massachusetts, andGEORGE K. VHEELER, of Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inSupports for Overhead Electric Conductors, of which the following, takenin connection with [O the accompanying drawings, is a specification. Ourpresent invention relates to supports for overhead electric conductors;and it consists in a hanger for suspending such wires, comprising a barprovided with suitable means of attachment for suspending the same byits middle, a groove in its lower edge to receive the conducting -wire,and two V-shaped or pointed cars at or near each end thereofone uponeach side of the wirethe same being constructed and adapted to be bentpartially around said wire to more securely fasten it to said bar.

Figure 1 is a side elevation of our improved hanger with a section of aconducting-wire secured thereto. Fig. 2 is a transverse section on lineas a: on Fig. 1. Fig. 3 is a transverse seetion on the same line beforethe conducting-wire is attached thereto, and Fig. 4 is alongitudinalseetion of a portion of one 0 end of said hanger before thewire is secured thereto.

In the drawings, A is the hanger, comprising a bar having a semicirculargroove to in its lower edge, the bottom of which groove is 3 5 astraight line, a rib Z) projecting upward from the groove-inclosingportion, which expands toward its center, where it is provided with theperforated ear 0 or other suitable means of suspending said bar from anysuitable in- 0 sulator.

At each end of the horizontal wire-supporting portion of the hanger areformed two V- shaped or pointed ears (1 clone upon each side of thegroove Ctl3h6 vertical length of fourth of the circumference of theconducting-wire 6, so that when wrapped around said wire their pointswill meet in the center of the lower side of the wire, as shown in Fig.2.

The hanger is made of brass and the inner surface of the groove aistinned, the conducting-wire is laid in said groove, the ears (Z (Z arebent around the wire, and then the bar and wire are soldered together.

The ears cl d, bent'around the wire, as described, add very greatly tothe strength of the attachment of the hanger to the wire, and by makingsaid ears pointed and thinner at their points than at their broaderparts they present but very little obstruction to the movement of thetrolley-wheel.

. That we claim as new, and desire to secure by Letters Patent of theUnited States, is

1. As a medium of support for an overhead electric conductor, a hangercomprising a bar provided with any suitable means of suspending the sameby its middle, having a longitudinal groove formed in its lower edge toreceive the conducting-wire, and two V-shaped or pointed ears at or neareach end-one upon each side of the wire-receiving groovesaid ears beingconstructed and adapted to be bent partially arouncLthe conducting-wireto secure said wire to the hanger.

2. In combination with an overhead conducting-wire, a hanger-barprovided with means of suspending it from any suitable insulator, withthe wire-receiving groove a, and the V-shaped or pointed ears cl d, bentpartially around said conducting-wire, substan- 8o tially as described.

In testimony whereof we have signed our names to this specification, inthe presence of two subscribing witnesses, on this 31st day of December,A. D. 1889.
